Research On The Location Selection Of City Public Service Facilities Based On Efficiency Evaluation

Public service facilities are basic social infrastructure that ensures the people's living standards and social harmony.With the growth of material resources and development of economy,there are more diversified and personalized demands toward public service facilities.Existing public service facilities are not sufficient to satisfy the growing demands.In addition,there exists a series of problems about current public services facilities that prevent them from achieving the planned objectives.The typical problems include unbalanced spatial distribution of resources,low efficiency of resource utilization,lack of quantitative research methodology,and inaccessibility by some residents,etc.This article discusses the location selection problem for public service facilities,which is a critical issue in the planning,construction and management of public service facilities.This article builds a model to select locations for public service facilities utilizing the covering-location model and key-players model.It explores how to select the best set of service locations among all the candidates to maximize the coverage with either limited or unlimited resources and different accessible distances,which usually vary in different practice problems.This article takes the location planning for water supplying station as an example.After deciding the services locations using the model we develop for planning locations of public service facilities,we define measures to evaluate the coverage efficiencies,and use data envelope analysis(DEA)to measure the service efficiency of each service location.Furthermore,we adjust the existing configuration model based on the measured efficiency to optimize the resource allocations.
